CompatHelper: add new compat entry for TrixiBottomTopography at version 0.1 for package docs, (keep existing compat)

[github-actions]

This pull request sets the compat entry for the TrixiBottomTopography package to 0.1 for package docs.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.
Note: Consider registering a new release of your package immediately after merging this PR, as downstream packages may depend on this for tests to pass.

@sloede @JoshuaLampert Do we need a compat bound like this in the docs/Project.toml neither Trixi.jl nor TrixiShallowWater.jl have such a compat.

[JoshuaLampert]

Yes, we don't need it. I'm honestly not sure why CompatHelper.jl suggests this here, but not elsewhere.

[andrewwinters5000]

Thanks, then I will close this PR and delete this branch.

[JoshuaLampert]

Oh, now I know. We don't need TrixiBT.jl in [deps].

[JoshuaLampert]

Thanks, then I will close this PR and delete this branch.

If we only close this PR, CompatHelper will create a new one. So I suggest to remove TrixiBT.jl from deps in docs/Project.toml.

[andrewwinters5000]

But that is weird. Both Trixi and TrixiShallowWater are in the deps for their respective docs/Project.toml?

[JoshuaLampert]

In Trixi.jl we have trixi-framework/Trixi.jl#2489 and in TrixiSW.jl CompatHelper is disabled: https://github.com/trixi-framework/TrixiShallowWater.jl/actions/workflows/CompatHelper.yml.

[JoshuaLampert]

In Trixi.jl we have a sources entry: https://github.com/trixi-framework/Trixi.jl/blob/e842dd265340a1524cc56b79ab270f745e9ea4b5/docs/Project.toml#L29. So it's fine to have Trixi.jl in [deps]. In TrixiSW.jl I would also recommend to remove it.

[andrewwinters5000]

Aha, gotcha. We can remove it here (as well as in TrixiSW most likely).
